Background: The flash glucose monitoring system (FGMS) has been a great advance in quality of life for patients diagnosed with type 1 diabetes (T1D). However, it is a more expensive method.Objectives: To describe the characteristics of the pediatric population (<18 years) diagnosed with T1D using FGMS, during one year in our community. To assess the degree of satisfaction and possible inconveniences. To evaluate the ...

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in childhood. Over the past decades, survival rates increased, but relapse is still associated with a poor prognosis, especially if the bone marrow (BM) is affected. Marrow adipose tissue (MAT) constitutes a major part of the BM niche, but its impact on normal hematopoiesis versus leukemia initiation, progression and relapse has only recently gained attention. MAT is very sensitive to changes in the patient’s...

Background: Biallelic mutations of the CYP11B2 aldosterone synthase gene cause deficiency of aldosterone synthesis. Patients exhibit isolated deficiency of aldosterone biosynthesis, increased plasma renin activity, increased steroid precursors desoxycorticosterone, corticosterone, as well as 18-hydroxy-desoxycorticosterone, and show salt wasting and poor growth. The aldosterone synthase enzyme has 18-hydroxylase (corticosterone methyloxidase type I, CMO I) and 18-oxidase (CMO ...

Background: The prevalence of vertebral fractures (VF) in Duchenne Muscular Dystrophy (DMD) is currently unknown as systematic spine imaging is rarely performed.Objective: To determine the prevalence of VF in DMD and factors associated with VF.Method: A prospective study utilising systematic screening with DXA vertebral fracture assessment (VFA) was performed in all 47 eligible boys. 6/47 were excluded due to spinal instrumentation...

Introduction: The term lipodystrophy describes a rare disease subdivided into a heterogenous group of even rarer subforms. The rarity of this disease makes research in this area extremely difficult and international co-operation is mandatory to accumulate data sets of sufficient size. The European Consortium of Lipodystrophy (ECLip) consisting of an association of European experts in the field of lipodystrophy has therefore decided to set up a registry for patients with lipody...

Background: This study aims to describe the predictive factors of severe obesity in children followed in French Guiana.Methods: In this observational study, the patients from the French Guianese Childhood Obesity Group database were prospectively included, after giving a statement of patient’s non opposition.Results: Our group classifications revealed that 36 of 150 (24%) participants were classified as being ...

Introduction: Growth prediction algorithms (i.e. iGRO), provide an estimate of a patients’ likely growth in the first year, and subsequent years, of GH treatment at a given dose, taking into account the patient’s combination of physical characteristics. Comparing a patient’s actual growth with their predicted growth after the first year of GH treatment, it is possible to determine whether the patient is responding to GH as expected (Index of responsiveness; IoR)...

Background: Individuals born with a 45,X/46,XY karyotype can present with diverging phenotypes from normal male, Turner-like to ambiguous genitalia, the latter classically being called mixed gonadal dysgenesis. No correlation between phenotype and degree of mosaicisms in the karyotype could be ascertained so far, making clinical management of these patients difficult.Objective: To understand, if androgen action through the androgen receptor (AR) is compr...

Background: Recently, patients with severe obesity have been described due to functional leptin deficiency. This new entity is characterized by high immunoreactive levels of circulating leptin (Lep), but a reduced bioactivity of the hormone due to defective receptor binding (N Engl J Med 2015;372:48–54). Since these patients can be successfully treated with human recombinant leptin (metreleptin), a diagnostic tool to detect functional leptin deficiency is needed.<p cl...

Background: Congenital adrenal hyperplasia (CAH) is a rare disorder of steroid synthesis. Patients have multiple health problems. Healthcare utilisation has not previously been assessed in the paediatric population with CAH.Objective and hypotheses: To assess healthcare resource use in patients in England with CAH.Method: The English Clinical Practice Research Datalink (CPRD) database is an observational and interventional research...
